Answer 1

Try this

var date = new Date("11/21/1987 16:00:00"); // some mock date
var milliseconds = date.getTime(); 
// This will return you the number of milliseconds
// elapsed from January 1, 1970 
// if your date is less than that date, the value will be negative

console.log(milliseconds);

EDIT

You've provided an ISO date. It is also accepted by the constructor of the Date object

var myDate = new Date("2012-02-10T13:19:11+0000");
var result = myDate.getTime();
console.log(result);

Edit

The best I've found is to get rid of the offset manually.

var myDate = new Date("2012-02-10T13:19:11+0000");
var offset = myDate.getTimezoneOffset() * 60 * 1000;

var withOffset = myDate.getTime();
var withoutOffset = withOffset - offset;
console.log(withOffset);
console.log(withoutOffset);

Seems working. As far as problems with converting ISO string into the Date object you may refer to the links provided.

Fixed the bug with incorrect conversion to milliseconds according to Prasad19sara's comment.

Yes, you can do this in a single line

let ms = Date.parse('2019-05-15 07:11:10.673Z');
console.log(ms);//1557904270673

Answer 3

Another solution could be to use Number object parser like this:

let result = Number(new Date("2012-02-10T13:19:11+0000"));
let resultWithGetTime = (new Date("2012-02-10T13:19:11+0000")).getTime();
console.log(result);
console.log(resultWithGetTime);

This converts to milliseconds just like getTime() on Date object

Answer 4

var date = new Date(date_string); var milliseconds = date.getTime();

This worked for me!
